CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and

result in failures not covered by warranty.

NOTE:

4. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are

at the specified temperature and are pulsed tests, therefore: TJ = TC = TA

Electrical Specifications

VDD = VIN = VEN = 3.3V, C1 = C2 = 10µF, L = 1.8µH, VO = 1.8V (as shown in “Typical Application Diagram” on

page 1), TA = -40°C to +85°C unless otherwise specified. Boldface limits apply over the operating

temperature range, -40°C to +85°C.
